Definitions

  • the present disclosure relates to systems and methods for controlling control plane and data plane traffic in a mobile network, and in particular systems and methods for decoupling control and data plane synchronization for Internet Protocol Security (IPsec) geographic redundancy.
  • IPsec Internet Protocol Security
  • Stateful geographic redundancy for network elements such as VPN gateways and ePDG, that terminate IPsec tunnels, requires synchronization of a large amount of long-lasting, per-tunnel state information between the active and standby nodes.
  • an active node may fail and the state of the user's session must be recovered at a standby node, which switches to an active role.
  • the standby node switches to an active role, it needs to program and activate various control and data-path functionalities as quickly as possible.
  • this programming phase can be inefficient and can take several seconds, leading to extended packet losses from which applications might not be able to recover.
  • standby nodes may store both control plane and data plane information.
  • both control plane and data plane functionality must be programmed and activated, leading to long recovery times.
  • maintaining “live” session information for both control plane and plane at a standby node is resource intensive for processors and memory.
  • Other recovery solutions employ a prioritization scheme that may recover certain prioritized sessions before recovering other, lower priority sessions, thus minimizing the impact of long recovery times.
  • IPsec state synchronization techniques that are explicitly designed for and take advantage of cloud-native or control/data plane separation architectures to improve efficient recovery and minimize interruptions to user plane activity are lacking.
  • FIG. 1 is a system diagram showing a geo-redundant networked system, according to some embodiments.
  • FIG. 2 is a system diagram showing a geo-redundant networked system, according to some embodiments.
  • FIG. 3 is a diagram showing an active geo-node and a standby geo-node, according to some embodiments.
  • FIG. 4 is a flowchart showing a transition between active and standby states, according to some embodiments.
  • FIG. 5 is a flowchart showing data plane and control plane state replication and switchover, according to some embodiments.
  • the present disclosure describes systems and methods for explicitly decoupling control-plane state synchronization from data-plane state synchronization.
  • a subset of the state parameters synchronized between active and standby nodes are essential for data-path packet processing functions, i.e. encryption and decryption of packets, whereas the remainder of the state parameters are needed for control-plane functions such as rekeying of phase-1 and phase-2 tunnels, dead-peer detection, SPI assignment, Mobility and Multihoming Protocol (“MOBIKE”) support, etc.
  • MOBIKE Mobility and Multihoming Protocol
  • Standby nodes will receive information related to the active tunnel control plane and active data plane from the active node. This information can be used by the standby node to replicate the tunnel that is at the active node.
  • the control plane data can be stored in an external database.
  • the data-plane component is programmed so that it can start processing packets as soon as a switchover is triggered.
  • the information necessary to program and activate the control plane component is stored until the switchover is triggered.
  • Programming can mean establishing a data channel that is immediately capable of processing data even though the data channel may not necessarily be actively processing data yet.
  • a switchover can be triggered by a network-anomaly.
  • a standby node can detect that the active node is no longer active by monitoring interfaces (e.g. BGP peering interfaces) connected to the standby node.
  • the standby node can infer that the active node is no longer active based on the communication link with the active node. For example, if the activity on the link indicates that the active node is inactive, the standby node can infer that a network anomaly has occurred and begin the switchover process.
  • the standby node can also detect that the active node is no longer active if it receives traffic that would otherwise be handled by the primary node.
  • the standby node can detect that the primary node is inactive by monitoring route weights managed by decentralized route optimization techniques. For example, an active primary node may report that its route cost is 5, while a standby node may report that its route cost is 10. In this first state, traffic is routed through the active primary node because its route cost is lower than the standby node. If the primary node is no longer active, its route cost may become 100. In this scenario, the standby node becomes the preferred route because its route cost is lower.
  • a switchover can be manually triggered (e.g. by direct communication via the EMS). After a switchover is triggered, the control-plane state can then be retrieved from the database and programmed on the standby control-node.
  • control plane information e.g. encryption keys, transforms, and other information on how to decrypt control packets
  • the decoupled synchronization described herein fits naturally in a control/data plane split architecture where there might be one or more control plane nodes separate from one or more data-plane nodes.
  • all the standby data-plane nodes can always be kept ready by programming them with the cryptographic keys needed for IPsec operation.
  • the switchover time is only limited by the routing convergence time as all elements of the distributed data plane would be ready to process the incoming IPsec packets.
  • the stack and resources (e.g. storage and processing resources) on the control-plane node(s) can be engaged only when they are actually needed.
  • the state information can be stored until then in a database. In some embodiments, the state information can, be stored on an external database.
  • control plane and data plane information allows one control plane to be associated with more than one data plane.
  • control-plane element and several data-plane elements only data-plane state needs to be synchronized to the data-plane elements.
  • data-plane state and control-plane state is needed at different points of time during a network-anomaly triggered switchover between standby to active roles, resources can be conserved, and session restoration time can be improved.
  • the control-plane state can be stored in an external database until the state is actually needed.
  • control plane information is stored in a common database that is accessible to both the primary and standby nodes.
  • the primary node may store the control plane information at the common database.
  • the standby database can retrieve the control plane information that was previously stored by the primary node in the common database.
  • the standby node is configured to receive the control plane information from the primary node and can store it either locally or in an external database.
  • the external database may be any database that is accessible to the standby node.

  • packets arrive at VePDG 104 and are processed successfully (e.g., data-plane active).
  • VePDG 104 control plane reads from the control plane database and rebuilds control plane state. From the control plane database, information about each IKE SA (security association) and IPSEC SA can be gathered. Information gathered can include remote IP address, SPIs used, encryption algorithms, time of last rekey, message sequence numbers, etc. Associations between IKE and IPSEC SA can also be built at this time. Rule lookup data-structures are also built at this time which can be very CPU intensive for a large number of tunnels. Note that no data-plane activity is required during this process and data flow is not interrupted. The control-plane rebuild process can introduce delay but will complete before the remote end to clears the tunnel due to timeout of control-plane messages.
